IMPROVEMENT IN HINGES.

Specification forming part of Letters Patent No. 212,149, dated Februaiy11, 1879 application filed December 17, 1878.

To all whom it may concern:

Be it known that I, JOHANN W. MORGE- NEIER, of Sheboygan, in the countyof Shehoygan and State of Wisconsin, have invented a new and usefulImprovement in Hinges, of which the following is a specification Thisinvention relates to a hinge constructed with beveledged flaps, set at aconsiderable angle with the vertical spindle or pivot-pin of the hinge.

The beveled edges of the flaps permit them to be pushed into dovetailedgrooves in the door andjamb, to which they areto be attached, andsecures them thereto without screws or nails, while the angle at whichthey are set forms a bracing support, which secures great strength witha minimum amount of material.

The invention will be readily understood by the accompanying drawings,of which Figure I is an elevation of the improved hinge, showin g it asit would appear when attached to a door and its frame and the doorthrown open. Fig. II is a sectional elevation of one of the flaps of thehinge, and showing it in position in the dovetailed groove prepared forit in a "door. Fig. III is an elevation of the inside of the hinge,taken by itself, with the two flaps separated, and showing the beveledge or dovetailed formation of the same.

The hinge consists of two flaps, A and B, which may be formed of eithercast or wrought metal. The flap A carries a spindle or pivotpin, a, inthe usual manner of butt hinges, and

the flap B carries a socket, I), which is made to fit to and turn on thesaid pin a, in the usual manner, These parts may be constructedso as toform either a right or a left hand hinge.

The flaps A and B are respectively set at angles of about thirtydegrees, more or less, with a line forming the vertical axis of the pina or socket I). K

This construction permits the said flaps to be'made quite narrow inproportion to the size of the hinge, and so forms, as it were, a bracing support, and secures the requisite strength with a minimum ofmaterial.

The top and bottom edges of the flaps A and B are respectively widenedfrom front to rear, so as to form the bevels a and b, which, when thehinge is attached to its door and easing, enter corresponding groovestherein, and so form a dovetailed attachment for the hinge without theaid of screws or nails to fasten it.

Having thus described my invention, I desire to claim- A hinge whoseleaves A and B are set at angles to the pin a and socket b, and areprovided with beveled edges a and 1), adapted to retain the hinge-leavessecurely in position without screws in recesses having undercut edges inthe door and joint, substantially as described and set forth.
